           Summary: Strange drawing around models in r600g in SC2
           Product: Mesa
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: ace@sannes.org


When playing a game of sc2 under wine, some models have a white sphere around
them.

This started happening after commit:
commit 43bdabd47d98975b56a759954fb5f37d2942c101

    mesa: fix vertex array enable checking in check_valid_to_render()           

    In particular, this fixes the case where a vertex shader only uses          
    generic vertex attributes (non-0th).  Before, we were no-op'ing the         
    glDrawArrays/Elements().                                                    

    This fixes the new piglit pos-array test.                                   

    NOTE: This is a candidate for the 7.10 branch.                              

I will attach two images, one where the commit is reverted.

My hardware is as follows:
ATI Technologies Inc RV770 [Radeon HD 4870]

Using r600g on gentoo ~amd64, with a 32bit chroot with r600g also.
